HORN-SUPPORTING ARM FOR TALKING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 705,165, dated July 22,1902. Application filed March 19, 1902. Serial No. 98,923. (No model.)

To all whrmt it 77mg concern:

Be it known that 1, Louis P. VALIQUET, a citizen of the United States ofAmerica, and a resident of the borough of the Bronx, city,

county, and State of New York, have invented certain new and usefulImprovements in I-Iorn Supporting Arms for Talking Machines, of whichthe following is a specification.

1 o My invention relates in general to soundreproducing apparatus, andmore particularly consists of an improved arrangement for supportinghorns of different length em ployed on such apparatus for magnifying thevolume of the reproduction of sound. As illustrated, the invention isapplied to that type of sound-reproducing apparatus employing asound-record in the form of a flat disk, though it may also be used withother forms an of talking-machines.

In the development of the talking-machine art the use of longer hornshas become general in order to increase the loudness of thereproduction. These require the use of long supporting-brackets, whichare liable to bend and sag under the very considerable weight of thelong horn. Moreover, the great length of the horn frequently brings thecenter of gravity of the whole apparatus outside of the gosupporting-base, with the result that the machine tips over when thelong horn is put in position. My invention overcomes these ditficultiesand also provides a construction in which horns of different length canbe supported from the same b1'acket-arm.

The preferred form of my invention is illustratedin the accompanying twosheets of drawings, in which Figure 1 is a side elevation of a machinehaving a long horn in position, certain parts being broken away. Fig. 2is a detail plan View of a portion of the swinging arm with the slidinghinge thereon. Fig. 3 is a side elevation and partial section of partsshown in Fig. 2. Fig. 4 is a detail plan View of a part of thesupporting-bracket, and Fig. 5 is a side elevation of the machine with ashort horn in position.

Throughout the several figures of drawings like reference-figuresindicate like parts.

The talking-machine consists of the usual casing 1, containing aspring-motor, which rotates the table 2 on which rests the sound-'-record 2. A bracket 3, attached to said casing, supports the swingingarm 4, which carries the sound-box 5 and horn 6, the outer end of whichis supported by the fork 7. The inner end of the bracket 3 has an eye 8formed therein and is attached to the motor-casing l by any suitablemeans, such as a thumb-screw 6o 9, passing through said eye.

The bracket 3 has a depending lug 10, in which is mounted a screw 11 orother adjustable part adapted to engage the side of the motor-casing.Preferably the screw 11 has a facing 12 of feltorothersoft materialwhich will not mar the polishof the motor-casing.

A depending support 13 has itsupper end resting in a socket 13, formedin the bracket 3, and is preferably held adjustably'therein by theset-screw 1-1. The lower end of the support reaches to the table orother surface on which the machine stands.

In the outer end of the bracket 3 is a socket 15, in which rests thepivot 16. A sliding block 17 is mounted on the arm 4: and corn nected tothe pin 16 by a hinged joint having a horizontal axis 18. The block 17carries the fork-7 and is held at the proper point on the arm 4 by theset-screw 19. The inter- 8o meshing portions 20 and 21 of the hingedjoint are so shaped that the motion of the hinge is limited in eitherdirection, as shown in Fig. 3.

The method of operating my invention is clear from the foregoingdescription. In shipping the machine the bracket 3 is detached from themotor-casing. When the machine is to be set up, the bracket is attachedto the motor-casing by means of the screw 9. The screw ll is then turneduntil the parts are all placed in a state of strain, which insures therigidity of the bracket with reference to the casing. The ornamental webextending from the under side of the bracket to the lug 10 serves alsoto give rigidity to the parts. The depending support 13 is placed inposition so that its lower end rests upon the table and is then clampedthere by the set-screw 14. If a long horn is to be used, the pivot-pin16 is placed in the socket 15, the sliding hinge block 17 is clamped tothe arm 4 at the proper point by means of the set-screw 19, the fork7 ismounted in said hinge-block, and the sound-box 5 and horn 6 placed inposition. If a short horn is to be used, the pivot-pin 16 is placed inthe socket 13*, with the resultant rearrangement of parts shown in Fig.5 to vary the effective length of the reproducer-arm.

The shapes of the interlocking portions 20 and 21 of thesupporting-hinge are such that they allow the necessary movement of thearm 4 and sound-box 5 to produce engagement and disengagement of thereproducer with the sound-record 2. If, however, the arm is swung to oneside of the record, its downward movement is checked in the positionshown in full line, in Fig. 3, before the stylus can strike the surfaceof the table on which the machine stands. If, on the other hand, the armis raised to the position shown in dotted lines in Fig. 3, the center ofgravity of the arm, sound-box, and horn will be shifted to the right ofthe axis 18 of the hinge, and further movement being checked by theengagement of the parts 20 and 21 the parts will remain in that positionof disengagement between record and reproducer while the record is beingchanged or any other desired operation is being performed.

The advantages of my invention comprise the stability of the machinewhen a long horn is used and the rigidity of all the parts, wherebyinternal vibrations and rattling, which tend to destroy the accuracy ofthe reproduction, are avoided, also the facility of using both long andshort horns with the same supporting apparatus, convenience in takingapart and assembling the different portions of the mechanism, and thegeneral ease and convenience of manipulation.

Of course various changes could be made in the details of constructionillustrated and described without departing from the spirit and scope ofmyinvention. The means of attachment of the bracket to the motor-casingmight be changed and also the form of the adjustable depending lug.Other forms of supporting devices might be substituted for the rod 13.Other forms of hinged joint and pivot connection mightbe employed anddifferent means for supporting the horn substituted for the fork '7.Other means for varying the effective length of the reproducer-arm mightbe employed. In case a short horn is used the support 13 may bedispensed with, as shown in Fig. 5. These and other changes which mightbe made, however, are merely matters of detail, and I should considerthe construction so modified as still within the boundaries ofmyinvention so long as the principles of construction above describedare retained.

Having, therefore, described my invention, what I claim as new, anddesire to protect by Letters Patent, is- I 1. In a sound-reproducingapparatus, the

tomes combination of the motor-casing, a bracketarm having an eye formedin its inner extremity and a downwardly-projecting lug thereunder,fastening means passing through the eye and engaging the upper part ofthe motor-casing, and'an adjustable extension of the before-mentionedlug adapted to engage the side of the motor-casing.

2. In a sound-reproducing apparatus, the combination of themotor-casing, a bracketarm having an eye formed in its inner extremityand a downwardly-projecting lug thereunder, fastening means passingthrough the eye and engaging the upper part of the motor-casing, and anadjustable extension of the before-mentioned lug adapted to engage theside of the motor-casing, together with a depending adjustable supportfor said bracket-arm.

3. Inasound-reproducingapparatus adapt ed to operate with a swingingreproducer and horn attached thereto, the combination of amotor-casing,a bracket-arm attached thereto, and means for pivotingthereto at various points in its length reproducer-arms of differentradii togetherwith a reproducer-arm whose effective length may bevaried.

4. In asound-reproducing apparatus adapted to operate with a swingingreproducer and horn attached thereto, the combination of amotor-casing,abracket-arm attached thereto, and means for pivotingthereto atvarious points in its length reproducer-arms of differentradii, together with a swinging repro ducer-arm having asupporting-pivot adjustable lengthwise thereof.

5. In a sound-reproducing apparatus, the combination of the rotatingrecord-carrying table, the reproducer, horn, and swinging arm therefor,the supporting-bracket, the vertical pivot-pin journaled therein, ahinged joint between said pivot-pin and arm having a horizontal axis,the intermeshing portions of said hinged joint being so shaped that themotion of the arm in a vertical plane is checked on either side, as thecenter of gravity of the horn and arm reaches a predetermined distancebeyond a perpendicular line drawn through the pivot.

6. In a sound-reproducing apparatus, the combination of a motor-casing,a bracketarm, means for fastening the inner end of said bracket-arm tothe upper surface of the motor-casing, and a depending lug from saidbracket engaging one of the sides of the motorcasing.

7. In asound-reproducingapparatus adapted to operate with a swingingreproducer, the combination of a sliding block adjustable on said arm,and pivot-pin hinged to said block.
